May 14, 1878 –
Robert A. Chesebrough begins selling Vaseline (registered trademark for petroleum jelly (U.S.
Patent 127,568.)
For the remainder of his life, he ate a teaspoon of the product every day.
(While he was president, Calvin Coolidge loved having his head rubbed with Vaseline while he ate his breakfast in bed.)
Insert dirty joke here (of course liberally lubricated with Vaseline.)
